Definitions

  • This invention relates to a modular cooling tower.
  • One common form of industrial cooling tower is a counter- flow tower in which warm water falls downward through one or more layers of fill or packing material, while cooler air moves upward through the layers of fill or packing material.
  • counter-flow refers to the fact that the warm water and the cool air are moving in opposite directions through the tower.
